The best of the week


One of the US Navy Band's ensembles performs in Wisconsin, 2009. Six performances by the Band were promoted to featured sound status. The Signpost thinks whoever pushed the bill through Congress to make US Government images and sound files free should be blessed; it has created a huge source of free cultural content.


This week's "Featured content" covers Sunday 15 – Saturday 21 May


New administrators

New featured picture, of video game designer and producer Robin Hunicke
New featured picture showing the result of the photographic technique of focus-stack microscopy. Here, the result of "stacking" the component images is a single image of a microfossil, at the bottom, with a depth of field almost impossible to achieve at high magnification.
From this edition onwards, The Signpost will announce new administrators at the start of the "In brief" section at "News and notes".


Four lists were promoted:

One featured list was delisted:


There were no new featured articles or delistings.


Four images were promoted. Medium-sized images can be viewed by clicking on "nom":

  • Warty crab (nom; related article), found in the Black Sea, Mediterranean Sea and eastern Atlantic Ocean. It has decreased in numbers since the 1980s and there are now concerns that it may be an endangered species. (Created by User:George Chernilevsky.)
  • Focus stack microscopy (nom; related article) of a diatom microfossil. Top left are the three source image slices at three focal depths. Top right are the contributions (black is no contribution, white is full contribution) of that focal slice to the final "focus stacked" image. At the bottom is the resulting focus-stacked image with an extended depth of field. Extended depth of field by focus stacking is a powerful tool for light microscopy as at high magnification the depth of field can be extremely shallow, down to around 1 μm. Stack Microscopy.

  • Grand piano diagram (nom; related article), a schematic horizontal cross-section of a major components of a pianoforte (part names are listed on the image description page). (Created by Polish user Orem; Orem on Commons.)
  • Robin Hunicke (nom; related article), a video game designer and producer known for her work with thatgamecompany and Electronic Arts. She has worked on games including MySims, Boom Blox and Journey. (Created by Charlie Chu; originally posted on Flickr.)


New featured picture: Polish user Orem's schematic of the grand piano, a design that has evolved continually over the 250-year history of the instrument, and which is still the subject of innovation. The labelled components are listed on the description page.
